> Paths returned from DFS internally cache their FileStatus, so that getStatus(Path) does
not require another RPC.  This cache is never refreshed and become stale, resulting in program
error.
> This should not be fixed until FileSystem#listStatus() is removed by HADOOP-2563, and
user code is thus no longer dependent on this cache for good performance.
